T0 or whom it may concern.-

Be it known that I, GUILLAUME LAURENCY, a subject of the King ofBelgium, and a resident of Brussels, Belgium, have invented certain newand useful Improvements in Continuous Spinning, Winding, and TwistingMachines, (for which I have obtained Letters Patent in Belgium, datedNovember 19, 1894, No. 112,834, and July 15, 1895, No. 116,303; inFrance, dated November 26, 1894, No. 243, 135; in England,dated November30,1894,

No. 23,284, and in Germany, dated November 24, 1894, No. 9,646,) ofwhich the following is a specification.

It has been generally recognized that with the continuous spinning-frameyarn cannot be wound upon a very thin spindle, as is done, for instance,in the self-actin g mule, at least without giving considerable twist tosuch yarn, in order that it may be solid enough not to break under thetension required to carry around the traveler, this tension augmentingin proportion as the diameter on which the yarn is wound becomesreduced.

The object of the presentinvention is to enable this inconvenience andthose which spring from it to be overcome, in order that yarns of anykind may be spun, wound, or twisted on a continuous spinning-frame witheither little or great torsion, as may be required, and may be wound inany form and size of bobbin or cop whatever may be the dimensions of thespindles or pirns on which the bobbins are to be formed.

With this end in view my invention consists in the improvementsillustrated in the annexed drawings, in which- Figure 1 is an elevationof a spindle, showing a cop in process of formation, also showing partof the ring-rail in section and an improved traveler thereon. Fig. 2 isa plan view of Fig. 1. Figs. 3 to 7 are sectional views of saidring-rail, showing alternative forms of traveler on the same principle.

In order to effect the objects of this invention, it is necessary toprovide means to twist and wind the yarn with a minimum tension which isconstant for all diameters of winding, and this is realized by thedevices hereinafter described, which have the following 4,1894,No.9,646;in FrancellovemberZS, 1894, No. 243,135,

peculiarities: first, keeping the yarn in a direction always favorableto the movement of the traveler, whatever may be the diameter on whichthe winding is taking place; second, varying the resistance of thetraveler; third, rendering this variation of resistance proportional tothe diameter of the bobbin or cop at the place of winding; fourth,realizing the three above-mentioned conditions while making the yarntraverse an invariable circumferential patl1-that is to say, one. thatis not modified by the difference of the diameters which the copsuccessively presents for the winding of the yarn, although the latteris always against the cop for all diameters. For these purposes I use animproved traveler and course for guiding it.

On the ring-rail P-namely, that part which has orifices P for thepassage of the spindles and cops and carries the devices by which thewinding is effectedI place in relation to the orifice P, through whichthe spindle passes, an annular plate A, having an inwardly-projectingannular flange B, so as to form between this flange B and the surface ofthe ring-rail P an annular re'cess or chamher A around the orificeaforesaid. This recess houses and guides the two ends of the traveler,which consists of a bar 0, adapted to lie across the orifice aforesaidwith one of its ends in the recess A at one side and the other end inthe'recess A at the other side. This bar 0 carries two hooks D and O,the former at about the center of its length and so placed that thetension on the yarn passing through it and drawn from it is directed ina line passing through the center of gravity of the traveler, the latterhook 0 near to that end of the traveler which is the leading end whenthe traveler is in motion. The latter hook O or its shank is adapted tobear against the face of the flange B-that is to say, against the wallof the orifice P-and it consequently constitutes an abutment for thetraveler, and to a certain extent also it performs the function of abrake or drag and of a pivot on which the traveler may turn. The

yarn passes first to .the hook G, thence to hook D, and thence to thespindle. When winding is taking place on the spindle itself or on thesmallest diameter of the cop, the traveler stands almost diametricallyacross the orifice P, and the pressure of the outer hook 0 against theflange B is then least, so that in this position there is the leastresistance to the rotation of the traveler about the spindle, but as thediameter of winding grows the traveler is displaced from the firstposition, Fig. 2, to the second or third position, and in proportion asit is displaced so the length of the chord of the circle of orifice Pwith which it coincides shortens. The hook 0 having bearing at one endof the chord the hook D becomes displaced more and more to one side ofthe center linenamely, the line passing through the axis of the spindleperpendicular to the line of extension of the traveler. This decreasesthe angle of the bend in the yarn around the hook D, and consequentlyincreases the drag on the yarn, giving thus an increased pressure of theouter hook 0 against the circular wall along which it moves. Theresistance of the traveler is thus proportional to the diameter ofwinding.

The thread draws the traveler by its center of gravitythat is to say, atthe middle point of its total weight. This point is also that at whichis concentrated the effort produced by centrifugal force. It is evidentthat this force which tends to throw the traveler away from the cop canbe entirely overcome by the tension of the thread which draws thetraveler toward the center axis of the cop. It is obvious, therefore,that it is desirable for the traveler to be able to rock on its axis, soas to lie closely to the surface of the cop, and it will be observedthat the traveler illustrated is quite capable of such rocking movementwithout in any way altering the conditions under which it has frictionalcontact in the ring.

The flange B may be made with a thickened or rounded edge, as at E, Fig.1, in order to have better control over the frictional resistance to themovement of the traveler which results from upward pull thereon by thetension of the yarn.

In place of making the hook C abut against the inside edge of the flangeB, as in Figs. 1, 5, 6, and 7, the leading end of the travelerbar 0 mayitself have abutment with the vertical wall within the recess Aaforesaid, as in Fig. 3 at H, or in place of that the said end may bebent up, as at J, Fig. 4, to run in a groove, as J, formed between twoconcentric ribs on the under side of flange B. By extending the hook D,as at N, parallel to or in the direction of the end of the travelerremote from its abutment the balance of the traveler under centrifugalaction may be modified.

The traveler may be made of steel or aluminium -bronze wire of anysection. The plate A may be metal, glass, or other material. Thecoefficient of friction between the hook O or its equivalent abutment onthe traveler and the annular wall against which it moves may beincreased by use of leather facings or equivalent material, as at M, onthe one or other of these parts.

I do not claim, broadly, a traveler consisting of a wire with hooks onenear the middle and one near one end and moving in an annular groove,but

I claim The combination with a spindle of a ringrail, a ring thereonconstituting an annular groove and a traveler consisting of asinglestraight bar adapted to extend across the orifice in the ringrail andengage with its leading and trailing ends in the annular groove, with ahook on said bar at the center of gravity of said traveler and a hookforward of the former hook in direction of the leading end of the saidtraveler, the traveler being adapted to rock on its longitudinal axisand to have frictionally-resistant contact at its leading end with thering whereby its center hook is displaced rearward of the line throughthe spindle-center perpendicular to the bar .of the traveler for adistance proportional to the diameter of the cop on which winding istaking place and may incline toward the cone of said cop for thepurposes set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
